Embodiment
Fig. 1 shows the wireless communication system 10 according to an execution mode.Subscriber equipment 50 is roamed in wireless communication system.Base station 20 is provided, and it supports wireless coverage area 30.Provide and a large amount of these base stations 20 that distribute geographically, in order to provide the wide area overlay area to subscriber equipment 50.When subscriber equipment is in the zone of serving base station 30, can based on relevant Radio Link, between subscriber equipment and base station, communicate.The a large amount of sectors in the geographic area 30 are typically supported to serve in each base station.
Different antennae in the base station is typically supported each relevant sectors.Therefore, each base station 20 has a plurality of antennas, and the signal that sends by different antennae is carried out electronic weighting, so that the sectorization method to be provided.Certainly will recognize that Fig. 1 shows the little subset of the sum of the subscriber equipment that may reside in the exemplary communications systems and base station.
Radio Access Network by radio network controller (RNC) 40 management of wireless communications systems.Radio network controller 40 is by communicating to control the operation of wireless communication system based on backhaul communication link 60 and a plurality of base stations.Network controller is also communicated by letter with subscriber equipment 50 via each base station.
The tabulation of radio network controller 40 maintenance of neighbor, it comprises the information of the geographical relationship between the sector of supporting about base station 20.In addition, radio network controller 40 maintenance position information, it provides the information about the position of the subscriber equipment 50 in the wireless communication system 10.Radio network controller can operate via circuit-switched network and packet switching network routing service.Therefore, provide mobile switching centre, wherein radio network controller can be communicated by letter with mobile switching centre.Mobile switching centre can communicate by letter with circuit-switched network such as public switch telephone network (PSTN) 70.Similarly, network controller can be communicated by letter with gateway general grouping support node (GGSN) with service universal grouping wireless serving GPRS support node (SGSN).GGSN can with packet-switched core network such as Internet traffic.
Many residential quarters high-speed downlink packet access (MC-HSDPA) configuration is provided in universal mobile telecommunications system (UMTS).In MC-HSDPA, be the geographical coverage area of base station or Node B with sector definition.The sector can comprise a plurality of residential quarters, and wherein each residential quarter is intended to cover the geography covering identical with the sector and is used the frequency carrier that separates to be used for its transmission.This frequency carrier can be among the identical frequency band or be distributed on two frequency bands.MC-HSDPA is the expansion of double small district high-speed downlink packet access (DC-HSDPA).In MC-HSDPA, subscriber equipment can receive nearly 4 downlink transmission from 4 different districts the time.Therefore MC-HSDPA can be potentially doubles the downlink throughput of DC-HSDPA and (single residential quarter) HSDPA respectively and quadruples.When transmitting when subscriber equipment receives respectively from 4 or 3 residential quarters, MC-HSDPA sometimes also is called as 4C-HSDPA (4 residential quarter HSDPA) or 3C-HSDPA.
In multicarrier system, each carrier wave will have the independently downlink wireless link from the base station to the subscriber equipment.Each carrier wave independently those downlink wireless links managed, because may have the different radio propagation path to subscriber equipment.For the HSDPA system that can operate in the multi-carrier mode, can provide more than two downlink carriers.Will recognize that in multicarrier network, the number of downlink carrier can not mate with the number of uplink carrier.The number of the downlink carrier that provides in addition, can not be just in time 2 times of number of the uplink carrier that provides.In the HSDPA multi-carrier mode, each sector of being served by the base station can have a plurality of carrier frequencies or associated " carrier wave ".Carrier wave or the geographic area identical with the sector covering, residential quarter of being supported by carrier wave.Each residential quarter is by different carrier frequency services.Therefore will be appreciated that in single-carrier system, the residential quarter is equivalent to the sector, because the sector only has a residential quarter or carrier frequency.But each sector can comprise a plurality of residential quarters in multicarrier network, and each residential quarter is served simultaneously by different carrier frequencies.
In MC-HSDPA, main carrier is the residential quarter of carrying the basic controlling channel and can not be deactivated.Only exist a main carrier and other residential quarters to be called as auxiliary carrier wave (for example auxiliary carrier wave 1, auxiliary carrier wave 2 and auxiliary carrier wave 3).
Can use HS-SCCH (High-Speed Shared Control Channel) order to realize the control of carrier wave.The HS-SCCH order is from supporting the base station to the ground floor signaling that allows to make quick order of subscriber equipment.Except the deexcitation of auxiliary carrier wave/activation, the HS-SCCH order also can be used for opening discontinuous sending and receiving.
Usually, the communication between the node occurs on a plurality of layers.In HSPA wireless access network (RAN), as shown in Figure 2, between network and subscriber equipment, there are 3 layers and communicate by letter.The 3rd layer is Radio Resource control (RRC), and the second layer comprises Radio Link control and media access control, and ground floor is physical layer.Each layer in network or the subscriber equipment will send the message of only estimating to go to the identical layer in subscriber equipment or the network.For example, come the RRC message (the 3rd layer of message) of automatic network only to estimate to go to the RRC at subscriber equipment place.Except physical layer (ground floor), all the message of other layers can not directly be sent to the respective layer on other nodes.For example come the 3rd layer of message of automatic network before sending to subscriber equipment, to need through the second layer and ground floor.At the subscriber equipment place, this message arrives its destination in the 3rd layer after ground floor is received and passes through the second layer.Shown in this example the 3rd layer of path that message takies in the arrow 100 in Fig. 2.
Usually, the rrc layer at the network place sends configuration messages and carries out particular task (for example switching to another residential quarter) with the order subscriber equipment.By radio network controller 40 control rrc layers, radio network controller 40 separates physically with Node B (NB).Therefore RRC message is usually slow.By sending these orders from the base station and can accelerate these orders in that physical layer (being ground floor) is upper because the base station can be on physical layer directly and communications of user equipment.In HSPA, use HS-SCCH (High-Speed Shared Control Channel), ground floor message is carried the order of going to subscriber equipment.The HS-SCCH order is so that the decision that base station and network place make can arrive subscriber equipment fast.Feature such as the quick service cell change that is used for allowing subscriber equipment to switch to fast the residential quarter is benefited from has the HS-SCCH order.The HS-SCCH order also is used for discontinuous transmission (DTX) and discontinuous reception (DRX) feature of On/Off subscriber equipment.In 4 carrier HSDPAs (4C-HSDPA), the HS-SCCH order is used for the auxiliary carrier wave of activation or deexcitation subscriber equipment.
Send the HS-SCCH order from the base station to subscriber equipment.For subscriber equipment, if it can also send the ground floor message that is used for carrying order or request to the base station, then be useful.For example the 4C-HSDPA subscriber equipment may wish to ask deexcitation auxiliary carrier wave in base station with conserve batteries.Current, up link ground floor message is only estimated for ground floor function (for example transmission power control command), rather than may be related to the order of the configuration in other layers.
Different from the HS-SCCH order, except serviced residential quarter received, the up link order also needed to be received by non-service cell (what namely participate in soft handover is not the residential quarter of main Serving cell) arbitrarily.The shortcoming of HS-SCCH order is that the base station need to be via any change of RNC 40 notice non-service cells to subscriber equipment, and this has caused delay.Its example is the activation/deactivation of the auxiliary carrier wave of up link among the DC-HSUPA (access of double small district High Speed Uplink Packet), wherein RNC 40 these activation/deactivation need to be notified in the base station, thereby RNC 40 can propagate this information to the whole non-service cells that belong to this subscriber equipment.Therefore, for the command/request that affects non-service cell, importantly the up link order also arrives whole non-service cells.
Therefore, present technique provides so that subscriber equipment can send to network the mechanism of ground floor or second layer order.This can realize with the multitude of different ways that hereinafter will describe in more detail.
Each up link order typically needs one or more in following field/information:
Identifier: be used for the subscriber equipment that sign sends this up link order;
Command type: this command type will illustrate whether Serving cell and/or non-service cell need to confirm and whether Serving cell and/or non-service cell need to move;
Order expression: the bit form that is used for representing concrete order;
Verification and: the base station is used for guaranteeing that it correctly receives the mode of this order.
Importantly by network some up link orders are confirmed.Existing E-HICH (E-DCH hybrid ARQ indicator channel) can be used for confirming the up link order.Similar with the HS-SCCH order, the up link order should not send with the E-DCH that carries user profile, because this will cause coming the conflict of the affirmation of automatic network.Also send existing E-HICH by non-service cell, it can be used for confirming the up link order.For the order that does not affect non-service cell or request (for example being used for the request of the auxiliary carrier wave of deexcitation 4C-HSDPA), subscriber equipment can be ignored the affirmation (perhaps non-service cell does not need to send the affirmation for the command/request of these types) from non-service cell.For the order that affects non-service cell or request, subscriber equipment will need to wait for the affirmation from whole services and non-service cell, and it just can be carried out afterwards, can continue command/request.
The up link order can also comprise whether service or non-service cell need the indication of moving arbitrarily.If the up link order is used for to one group of non-service cell transmission of information, then any one in service or the non-service cell may not need to move.Whether it can also be indicated need to be from the affirmation of service or non-service cell.This will reduce the unnecessary affirmation that comes automatic network.
Need to send the up link order with the power that can arrive the non-service cell with the poorest radio condition.For example, can be with sending the up link order than the power that sends the high X dB of the needed power of up link order to Serving cell.Can be by network configuration value X.
In this is realized, provide new physical channel to carry up link order and/or request.The form of the new definition of up link command channel utilization or can multiplexing existing physical channel form.Multiplexing existing form has the advantage that need not its link performance is carried out uniformity test, because it will have identical link performance with the existing form of having tested.But in this case, the up link order will be limited to the number of the information bit of existing physical channel.Current HS-SCCH order only has 6 bits and represents order, provides at most 64 different orders.Particularly when introducing needs 27 orders to come the 4C-HSDPA+4C-HSUPA of 4 down links of activation/deactivation and uplink carrier, these different orders will be exhausted fast.Therefore the physical channel that is used for the new definition of up link order should comprise that at least 6 bits are with the expression command/request.To provide new spreading code so that information is encoded.Can use existing or new coding/decoding scheme.Similar with the HS-SCCH order, the up link order should comprise that the CRC (cyclic redundancy check (CRC)) for error checking orders to avoid mistranslating.Also need to be from the affirmation of base station when receiving order.
In up link, can order to carry the up link order by multiplexing existing HS-SCCH, because it has had the needed most elements of order.But, be used for subscriber equipment because HS-SCCH is designed to decoding, so the performance that may need to test it at the place, base station.Also may need new coding strand at the subscriber equipment place.
The advantage of this realization is that there is flexibility in the number of the bit that provides in message, and can be so that Code And Decode is more effective.Shortcoming is that the base station needs new decoder chain; Subscriber equipment needs new encoder chain; The base station needs new searcher (to find out this new channel); And need new uniformity test to test this channel.
In Fig. 3, shown an example format.Here:
ACK_REQ: comprise 2 bits, and be used to indicate the service or non-service cell whether need to confirm.This is as hereinafter describing in more detail.
ACT_REQ: comprise whether service or non-service cell need 2 bits that move.This is as hereinafter describing in more detail.
The additional command head.
The order expression.Each unique bit form definition related command.
CRC check and.CRC check and can be existing 24 bits that use among 16 bits or the E-DPDCH.
Because this is ground floor message, so identify UE by employed scrambler.
Realize 2---utilize E-DPCCH and E-DPDCH by correction
E-DCH (enhancement type special channel) is the transmission channel that carries for the user data of HS-UPA.It comprises such as the E-DPCCH that shows among Fig. 4 (E-DCH Dedicated Physical Control Channel) and one or more E-DPDCH (E-DCH Dedicated Physical Data Channel).Two physical channels among the E-DCH are designed to operate in the soft handover, and thereby non-service cell had their ability of decoding.E-DPDCH carries user profile, and E-DPCCH carries the control information that comprises for the decoding instruction of attached E-DPDCH.For fear of having additional uniformity test, the up link order can multiplexing existing E-DPCCH form.E-DPCCH comprises 10 information bits, and it can be used for representing the up link command/request.But E-DPCCH does not comprise error checking and correction, because it is to comprise that 24 bit CRC are as the part of the E-DCH of the part of its coding.Carry CRC by E-DPDCH.In order to support error detection occurs, can be with send the up link order of using E-DPCCH for the selectable E-DPDCH that carries CRC.E-DPDCH can be selectable, because some up link orders or request may not need CRC (for example asking the auxiliary carrier wave among the deexcitation 4C-HSDPA).The set that reduces of E-TFCI can be used for E-DPDCH and its can carry additional information for the up link order.Utilization is expanded be used to the E-DPCCH that carries the up link order with the spreading code that the spreading code of being used by existing E-DPCCH separates, thereby the base station can be distinguished by between.
Therefore, this is realized by having revised existing E-DPCCH multiplexing and E-DPDCH pair.E-DPCCH will distinguish himself and existing E-DPCCH with different spreading codes.Corresponding E-DPDCH can be selectable (at the E-DPCCH indicating), and if its be sent out then can use a plurality of different forms at E-DPDCH.
The advantage of this realization is, can use the order of flexible in size; Do not need new decoder or encoder chain; Do not need new uniformity test.Shortcoming is that the base station needs new searcher (to find out this new spreading code); And order need to be decoded to obtain to two channels in the base station.
Shown an exemplary form among Fig. 5.Here:
On E-DPCCH: the ACK_REQ that comprises 2 bits is used to indicate service or whether non-service cell needs to confirm, as hereinafter describing in more detail.
On E-DPCCH: the ACT_REQ that comprises 2 bits is used to indicate service or whether non-service cell needs to move, as hereinafter describing in more detail.
On E-DPCCH: E-DPDCH is attached.Indicate whether to exist the E-DPDCH that is attached to this order with 1 bit.
On E-DPCCH: order or E-TFCI.If there is no E-DPDCH is attached, and then 5 bits represent order.Otherwise this will be the E-TFCI that uses among the attached E-DPDCH.
On E-DPDCH: command header.
On E-DPDCH: the order expression.
On E-DPDCH: the CRC of 24 bits.
Send ACK_REQ and ACT_REQ, the E-DPCCH because will at first decode in the base station at E-DPCCH.This will allow service or non-service cell to determine their attached E-DPDCH (if present) that whether needs to decode.For example, if ACT_REQ indication need to be from the action of non-service cell, the non-service cell E-DPDCH that will further not decode then.
Because this is ground floor message, so identify UE by employed scrambler.
Realize 3---utilize independently E-DPDCH
The E-DPCCH that utilization has an above-mentioned attached E-DPDCH causes base station two physical channels (may do like this although the base station is current) of must decoding.And, also need secondary power to carry two physical channels for the up link order.For fear of this situation, the up link order can be used independently E-DPDCH.Here, E-DPDCH uses fixedly E-TFCI, spreading factor (SF) and control routine, thereby can decode in situation about need not from the arbitrary instruction of E-DPCCH.The up link order can be used the minimum transfer block size for the E-DPDCH (E-TFCI=0) of 18 bits, and this is larger than existing HS-SCCH order.But, can use other predetermined E-TFCI.Existing (24 bit) CRC among the E-DPDCH can be used further to error detection occurs.The E-TFCI=0 initial design is for carrying the MAC schedule information, its be robust and therefore be applicable to carry the up link order.
Existing uniformity test is only tested E-DCH (enhancement type special channel) channel rather than its component E-DPDCH or the performance of E-DPCCH among the 3GPP.Do not need additional testing for E-DPDCH independently, because expect that its performance is better than E-DCH (i.e. E-DPDCH and the E-DPCCH of combination).This is because the failure among the E-DPCCH will cause the failure among the E-DPDCH, because decoding instruction will be lost in the base station.Use the independently up link order of E-DPDCH will have the known decoding instruction at the place, base station, this is equivalent to desirable E-DPCCH.
E-DPDCH will use different spreading codes and set form, thereby the base station knows how to search and decode it.An exemplary form is to have the form that uses among the E-TFCI=0 of 18 bits.
The advantage of this realization is, does not need new decoder and encoder chain; Do not need new uniformity test; And base station 1 channel of only decoding.Shortcoming is that the base station needs new searcher (to search new spreading code); And the up link order has fixed size.
Shown an exemplary form among Fig. 6.Here:
ACK_REQ: whether comprise 2 bits, being used to indicate service or non-service cell needs to confirm, as hereinafter describing in more detail.
ACT_REQ: whether comprise 2 bits, being used to indicate service or non-service cell needs to move, as hereinafter describing in more detail.
The order expression.Each bit form definition order (at least 6 bits).
24 bit CRC check and.
Command header and order expression comprise 14 bits together.Because this is ground floor message, so identify UE by employed scrambler.
Realize 4---in uncorrected situation, utilize E-DPCCH and E-DPDCH
As mentioned above, E-DPCCH or independently E-DPDCH with different spreading codes will need additional decoder/searcher to detect this channel at base station place.For fear of this situation, can multiplexing existing E-DCH.Indicating corresponding E-DPDCH with untapped E-TFCI among the E-DPCCH here, is the up link order.With independently E-DPDCH is similar, this E-DPDCH will use fixedly spreading factor and fixed transport block size here.Although different forms has different not use E-TFCI, it is the indication of up link order that the base station can be programmed in each form concrete E-TFCI (being untapped E-TFCI) is identified as E-DPDCH corresponding to indication.But the method will only be applicable to 2ms TTI HSUPA in general manner, exists only among the 2ms TTI HSUPA because untapped E-TFCI is current
Therefore, this realization is similar to multiplexing existing E-DPCCH and the right realization 2 of E-DPDCH.But with new spreading code itself and existing E-DPCCH and E-DPDCH are not distinguished.It is the up link order that untapped E-TFCI bit form is used to indicate corresponding E-DPDCH.E-DPDCH typically uses set form and preferably has form (for example E-TFCI=0) now.
The advantage of this realization is, does not need new searcher; Do not need new decoder and encoder chain; Do not need new uniformity test.Shortcoming is that the method may be only applicable to 2ms TTI option, has a untapped E-TFCI bit form because only 2ms TTI is current; The up link order will have fixed size, because only 1 untapped bit form can be used; And two channels of base station decodes obtain this order.
Shown an exemplary form among Fig. 7.Here:
Do not change at E-DPCCH, existing happy bit, retransmission sequence number (RSN) and E-TFCI do not change.It is the up link order that untapped E-TFCI bit form is used to indicate attached E-DPDCH.
The E-DPDCH hypothesis for example comprises the form of the E-TFCI=0 of 18 bits.Therefore this structure is similar to the independently structure of E-DPDCH.
Because this is ground floor message, so identify UE by employed scrambler.
Realize 5---the correction of the second layer
Except having the realization of ground floor physical channel, second layer channel massage also can be used for carrying the up link order such as short RLC or MAC message.In HSPA, the second layer is positioned at the place, base station, and does not therefore need to arrive by RNC 40 non-service cell of UE from the second layer message of subscriber equipment.In addition, (for example E-DCH) carries MAC message by existing uplink channel, thereby avoided additional consistency performance test.
For example, carry uplink signalling by second layer MAC message.MAC message should comprise be used to indicate a field that it is order (namely reshuffling with wireless), be used for sign send this order subscriber equipment identifier and should order itself.Because this order is in the second layer, so it can be carried by existing physical channel.
The advantage of this realization is, the flexible in size of order; Do not need new searcher; Do not need new decoding or coding strand; Do not need new uniformity test.Shortcoming is that the up link order slowly arrives the base station, because it is in the second layer; Confirming may be slowly (may be that RLC confirms---subscriber equipment may be implemented as for this situation confirms that with ground floor (for example E-HICH) confirms to process as the second layer).
Shown an exemplary form among Fig. 8.Here:
ACK_REQ: comprising 2 bits, whether need confirm, as hereinafter describing in more detail if being used to indicate service or non-service cell.
ACT_REQ: comprising 2 bits, whether need move, as hereinafter describing in more detail if being used to indicate service or non-service cell.
Additional command header.
The order expression.Order of each bit form definition.
The UE identity.Use UE 16 bit E-RNTI here.
Can carry this second layer message by E-DPDCH, and therefore do not need verification and, because physical layer (being E-DPDCH) will carry out this verification and.
Exemplary operation---situation 1
Fig. 9 and Figure 10 show the example networks operation when utilizing the up link order.In this example, carried by existing E-DCH channel and by the order of untapped E-TFCI indication up link.The E-DPDCH decoding instruction is fixed, and is that the base station is known and can be as follows:
1) spreading factor (SF) 256;
2) E-TFCI=0 (18 information bits).
Whether some up link orders or request do not need to confirm, and therefore use (18 available bits in) two bits to indicate service and/or non-service cell to need to confirm.As a reference, these two bits are called as ACK_REQ, wherein, (can utilize other coding techniquess) in this example:
ACK_REQ=" 00 " means need to be from the affirmation of service and non-service cell;
ACK_REQ=" 01 " means the affirmation that only needs to come non-service cell;
ACK_REQ=" 10 " means only need to be from the affirmation of Serving cell;
ACK_REQ=" 11 " means need to be from the affirmation of service and non-service cell;
Need to indicate whether the action of service and/or non-service cell with two other bit.As a reference, these two bits are called as ACT_REQ, wherein, (can utilize other coding techniquess) in this example:
ACT_REQ=" 00 " means the action that does not need to serve with non-service cell.
It can only send as information.
ACT_REQ=" 01 " means that only non-service cell needs execution action.
ACT_REQ=" 10 " means that only Serving cell needs execution action.
ACT_REQ=" 11 " means that service and non-service cell need execution action.
Now the hypothesis subscriber equipment is striden as shown in Figure 9 two frequency band operations in 4C-HSDPA.Subscriber equipment wishes that conserve battery power and decision close the auxiliary carrier wave (auxiliary carrier wave 2 and 3) in the auxiliary frequency band.
As shown in Figure 10, subscriber equipment sends request via the up link order with ACK_REQ=" 00 " to its base station because its only be request and from the action of Serving cell as the affirmation for order.ACT_REQ is set to " 10 ", because only need the action (being the HS-SCCH order) of Serving cell.Service and the order of non-service cell receiving uplink.Because ACK_REQ=" 00 ", so the residential quarter does not send affirmation.Because ACT_REQ=" 10 ", so this request only relates to Serving cell and does not therefore need non-service cell to move.Serving cell is determined its safely auxiliary carrier wave 2 of deexcitation and 3 and send the HS-SCCH order with these carrier waves of deexcitation.Subscriber equipment is confirmed this order and is continued the deexcitation target carrier.
Exemplary operation---situation 2
Figure 11 and Figure 12 show the example networks operation when utilizing the up link order.In this example, use with situation 1 in identical up link order.The following carrier wave that 4C-HSDPA has as being shown as " initial configuration " among Fig. 1 arrives frequency configuration.Here, CP refers to main carrier, and CS1, CS2 and CS3 refer to respectively auxiliary carrier wave 1, auxiliary carrier wave 2 and auxiliary carrier wave 3.In Figure 11, CP is attached to frequency F2 at first.In this example, suppose that one of its movable auxiliary carrier wave might be changed into the main carrier of subscriber equipment via the HS-SCCH order in the base station in the 4C-HSDPA network.Base station (being Serving cell) determines CP is changed among Figure 11 the F1 that is shown as " target configuration " from F2.
Shown in the signaling diagram among Figure 12, the base station sends HS-SCCH and orders to change main carrier.Subscriber equipment receives the HS-SCCH order and sends affirmation to the base station as Serving cell.Because the change of main plot affects non-service cell, so subscriber equipment sends the up link order with the change of notice non-service cell main carrier.ACK_REQ and ACT_REQ are set to " 01 ", and therefore only non-service cell need to send and confirm and execution action.Therefore non-service cell knows that subscriber equipment will change into F2 to its main plot from F1, and confirms this up link order via E-HICH to subscriber equipment.Serving cell does not need action.Receive from non-service cell affirmation (E-HICH) afterwards, subscriber equipment continue to change its main carrier (notice if having a plurality of non-service cells then same up link order will arrive other non-service cells).
Therefore, the up link order is as the mode that is used for the change of notice non-service cell main carrier.This has exempted Serving cell must be via RNC 40 notice non-service cells, and this may be consuming time and may interrupt communicating by letter between non-service cell and the UE temporarily.
The more detailed order of the method support and request and can be used as the quick ground floor signaling of non-service cell, this has alleviated prior art does not have enough bits and comes relaying to need the order of additional information (for example which auxiliary carrier wave of deexcitation in 4C-HSDPA UE) and the problem of request.
